Specification of Letters Patent. Application filed January 9, 1909.

Patented .rune 1, 1909. Serial No. 471,607.

To all whom 'it may conci/rn:

Be it known that I, HERRMANN Linrz, a citizen of the United States of America, residing at Pittsburg, vin the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Trolleys, of which the followingis a specification, reference being had therein to the accompanying drawing.-

This invention relates to trolleys,V and the object of my invention isto provide a novel device to assist the replacing. of a trolley wheel upon a trolley wire, should the same be accidentally' displaced due to irregularities in the wire, rapidity of operation or curves in a railway system.

My trolley replacing device is constructed to normally retain a trolley wheel 1I on a trolley wire, which is made whereby tliie device can recede when encountering trolley hangers and all overhead work of a railway The detail construction entering into my invention vwill be hereinafter described and then specifically claimed. 'i

Referring to the drawings z-F igure 1 is a side elevation of atrolley device, and Fig. 2 is afront elevation of the same.

In' the accompanying drawings, 1 designates a trolley pole having a harp 2, between the arms 3 of which is journaled a trolley wheel .4, said wheel being adapted to travel upon awire. The' arms 3 extend above the periphery ofthe trolley wheel, 4 and are beveled inwardly, as at 6.

The sides of the harp 2 are provided with depen ing parallel anchor-shaped plates 7, the anchor ends of which are connected, as at 8, and provided withapertured luos or eyelets 9. Pivotally connected to thezh'arp 2 by a bolt 10 and a nut` 11 are replacer arms 12, said arms extending -upwardly above. the harp arms 3 and flared outwardly, as at 13, at an angle corresponding to the bevel of the up er ends of the harparms 3. The lower ens of the replacer arms 12 are provided -with eyelets 14 and these eyelets are connected .by coil springs 15 to the apertured lugs or eyelets 9. lThe tension of the 's rings 1.5 is adapted to normally lacer arm's12'parallel with the arms 3 of the terecl,

. said maintain t erefl f springs 15 will return said replacer arms to t ieir normal position. The lower inner edges of the replacer arms 12 are provided with inwardly rojecting guides' 16 extending upwardly inside of the anchor-shaped plates 7, to prevent the arms 12 from wabbling.

My trolley replacer is made of'metal and is p pplicable to the present type of trolley ar vghile in the drawings forming a art of this application there is illustrated t e pre-A ferred embodiments of my invention, I would have it understood that the same can be varied or changed as to shape, proportion and manner of assemblage from the spirit of ,the invention.

Having now described my invention what I claim as new, is

1. The combination with a trolley pole, a

harp carried thereby and having a wheel liournaled between the arms of said harp, of anchor-shaped plates fixed to the outer sides of said har a ertured lugs carriedy by the anchor endg oi) said plates,`replacer arms pivotally supported by thesides of said harp and having .the upper ends thereof fiared outwardly above the periphery of said trolley wheel, eyelets carriedby4 the lower ends of said replacer arms, springs connecting said eyelets to the pierced lugs of said anchor plates, and inwardly' extending guides oarried by the lower edges of said replacer arms and extending upwardly at the inner sides of said anchor plates for guiding the movement of said replacer arms, substantially as de scribed. 2. The combination with a trolley harp, a

'trolley wheel journaled between said harp', of

anchor plates securedito the sides of said harp, replacer arms'pivotally carried by the sides of said harp and having the upper ends without departing thereof extending above the `periphery of 'saidwheeh guides carried by the inner lower edges of said replacer arms and adapted to embrace the lower edges of said anchor plates, and means connecting the lowerends of said replacer arms andthe anchor ends of lates for connecting said replacer arms para el with said harp. ,.1 j vIn testimonywhereof I affix 'my' signature inthe presence of two witnesses. arpl 2 and" when-a cross wire, trolley hanger or similar overhead construction is encoun the upper ends of the arms 12 can re,l 65 cede tofpass-such' 'structuraand .thenlthe
